  • Have a trailer with 600 lbs – 1,200 lbs of tongue weight that often veers out of line with your vehicle

No, if you:

  • Don’t have a lot of space to work with on your trailer frame, or if the frame is thicker than 2-1/2”
  • Have a boat trailer with surge brakes or an aluminum frame
  • Hate noise - the bars popping in and out of the cams can create a racket, especially during turns

Weight Distributing Hitch

Create a stable ride for your tow vehicle and trailer with a weight-distribution hitch. Adding spring bars to your towing system applies leverage, which transfers the load that is pushing down on the rear of your vehicle to all the axles on both your tow vehicle and your trailer, resulting in an even distribution of weight throughout. The result is a smooth, level ride, as well as the ability to tow the maximum capacity of your hitch.

Selecting a Weight-Distribution System

The tongue weight rating is the most important factor in determining which size weight-distribution system you should use. If the bars of the system you choose are rated too high for your setup, they will create a rigid ride, which can result in a bouncing trailer. If, on the other hand, the bars are not rated high enough, the system will be unable to properly distribute the weight, rendering it virtually useless.

To determine the proper weight rating for a weight-distribution system, you must first determine your trailer's tongue weight. Then add to that the weight of the cargo behind the rear axle of your tow vehicle. These two measurements make up the tongue weight rating for a weight-distribution system.

Serrated Washer System

Unique Features of Reese Strait-Line Weight Distribution

The easy-to-use, serrated washers on the Reese Strait-Line system make adjusting the tilt of the weight-distribution head a snap. This is a huge improvement over the standard pin-and-washer method, which involves piling washers - one on top of another - onto a difficult-to-access pin. The serrated-washer system lets you easily loosen, adjust and tighten a single washer and nut on either side of the head for simple, secure positioning.

The trunnion spring bars of the Strait-Line system slide into the weight-distribution head for quick, easy installation. With a tapered design and hot rolled steel construction, these bars offer superior flex, ensuring a smooth, controlled ride for both your tow vehicle and your trailer. These specially designed bars have rounded, hooked ends, making them the only kind of spring bars that can function with Reese's active-style, dual-cam sway control.

Weight Distributing Hitch

Dual-Cam Sway Control

Reese's dual-cam sway-control system stops trailer sway before it begins. This is a significant improvement over traditional friction-style controls, which help to correct sway only after it has already begun. This specially designed system uses unique sliding devices called "cams" to suspend the spring bars of your weight-distribution system. One end of a cam bolts onto your trailer's frame, and the other end attaches to the lift bracket via the lift chain. The rounded, hooked ends of the spring bars then sit in these cams. The controlled placement of the spring bars keeps your system secure while still allowing enough movement for free, easy interaction between your trailer and your tow vehicle.

Dual-Cam Sway Control Turning

During basic, straight-line towing, the cams lock in place and hold the trailer steady by applying constant, consistent pressure to both sides. This keeps the trailer from swaying in crosswinds. When you go into a turn, the cams unlock and slide to allow a controlled, full-radius maneuver. If you swerve suddenly, the cams will give to accommodate the movement while still working to obtain a straight angle, thereby maintaining control of the trailer.

Average Customer Rating:  4.8 out of 5 stars   (297 Customer Reviews)

Featuring dual-cam sway control, this weight-distribution system includes an adjustable shank and flexible, powder coated steel, trunnion spring bars to create a level ride for both your trailer and your tow vehicle. Fits 2" trailer hitches.


The product was not only a perfect physical fit for my truck and travel trailer, but it it works so well I no longer drive with white knuckles. The etrailer support team worked with me to figure out my real needs versus my preciously rookie "wants" which were somewhat uninformed wants. My Trunion Bar WD Hitch with Optional sway control makes ZERO noise in use or backing up, nor does it impart any felt knuckling.

Absolutely the best working hitch ever. No noise, clacking and knuckling like friction hitches. The sway control is amazing.
Steve M - 08/20/2020


OK, I waited to write this review until I had an opportunity to really use this product. We just completed a 950 mile camping trip around Colorado. We went up and over mountains, around curves, and traveled in the interstate. All I can say is, WOW! I wish I had purchased this years ago. We pull a 7000# travel trailer with a new F150 EcoBoost. Before installing this we were pushed around in windy canyons, semis and dealt with sway descending the mountains. This product is the real deal. I can safely travel on the interstate at speeds up to 75 MPH thanks to this product.

I have a 33 TT towing with an ecoboost. I think the hitch I have is too week. My TT never gets loaded over 6,500 yet I still get a bad front end drift? I think its the WD I currently have. Does this hitch really solve that problem? My TV is a super crew lariat off road package with c rated tires
-- comment by: Josh - 08/08/2014

Weight distribution can help handling and steering when properly set up. This system also has an integrated sway control system also improves handling and stability. With your travel trailer loaded and ready to go, having about 650 pound of tongue weight, this system is rated appropriately for your needs. If you are experiencing too much front end sway you may need to make some adjustments to place more of the load on the front axle These adjustments can be made at the angle of the head. Please see your specific installation instructions for more details.

-- Etrailer Expert Rachael H - 8/12/2014


I've been very happy with the system that we got, we put almost 7,000 miles on it in 2017 and it rode great. I added a secondary friction sway control to compliment the control provided by the leveling bars and cam assembly and over those miles it never felt uneasy. A couple of times we were in some pretty good cross winds and I would notice enough to put two hands on the wheel but the rest of the time it was almost easy to forget we were towing a 28' trailer.
I'd definitely recommend spending a little time at your local Cat Scales to find out your specific truck / trailer and tongue weights, but this hitch and distribution assembly gave us the ability to tune the tongue weight into right where we wanted by the selection of the right link.
The peace of mind the overall control that it provided going down the road is well worth it.


Great customer service. I contacted support to check on delivery date and mentioned I was picking up a new trailer. The order was immediately pulled and shipped and arrived on time.


We bought a very large travel trailer after having owned on before. With the first camper I eventually ended up with a Reese cam sway control as the only way to control sway in Kansas cross winds. I made the mistake with our new camper of following the recommendation of the dealer on a hitch for the new camper (36ft 9600lbs unloaded). It was really just a variation of equalizer bars and man what a mistaKe that was! I looked for the Reese cam system but wasnt finding it in my searches - then realized they changed the name to the Strait-line. This thing is amazing! What a difference in the wind. And you back up without doing anything to the hitch which I guess can be an issue with 4-points. When setting it up follow the instructions to the letter, and always think “keep thongs symmetrical.” It wont disappoint. Love it.


I have used the Reese weight distribution and sway control system twice now over the past year to tow a 6K pound, 30'Jayco travel trailer with my 2014 4x4 Tundra Platinum (which had, at the time of purchase, the largest tow capacity of any 1500 truck on the market). Before having the system installed, the trailer felt like a sail behind my truck and was pushing me around - felt like I was navigating an ocean liner. After the system was installed, I've taken the trailer over one of the most challenging (and beautiful) highways in the country - HWY 299 in Humboldt/Trinity County, California. This trek has steep grades, many poorly-banked hairpin turns, and gusty conditions, and I could barely tell I was towing anything. Huge difference in performance, and tremendous improvement in my peace of mind. Would highly recommend the system.
Note: I also have an aftermarket brake controller on the Tundra as the '14 model didn't come with an integrated controller. In TOW-HAUL mode, that truck has no problem in the muscle department towing that trailer, just needed the extra security/stabilization of the Reese system.


Pulled an 11,000 lbs enclosed trailer from Arizona to Rhode Island. Once I got the load adjusted, I didn’t have enough weight on the tongue, it worked well. I’ll buy it again and would recommend it.


OMG, the Reese straight-line weight distribution hitch is fantastic. No complaints whatsoever. Pull a 23 foot Rockwood trailer of 3,200 pounds with my 2016 Ram 1500. Pass the semi-trailers with confidence and absolutely no white knuckles. Great product.

Fantastic hitch!

I had experience with towing travel trailers before, but it had been a while. When we decided to buy a new trailer, the hitch setup the trailer dealer proposed just didn't seem right for the job. Doing some research on my own, I came across the site. From the information that was available on the site I was able to focus in on what I thought would be the best fit for my F-150 towing an 8,000 lb + trailer. When I called with questions, I was fortunate that I talked to Wayne--one of etrailer's product specialists. This was like talking to a trusted brother. We discussed a few different brands and the pros and cons; but in the end decided the Strait-Line RP66084 would be the best fit. After that conversation, I did some more research on my own and--besides discovering that Wayne's advice was fantastic and spot on--found that the Strait Line system proposed was top ranked. The features I was looking for: (1) Leveling (weight distribution) capabilities (2) Sway control (3) Safety (4) Tracking (holding the trailer steady behind you when taking curves (5) Ability to back up without having to get out of truck and manually release a brake bar and (6) simple enough to install for a shade tree mechanic. The Strait-Line fit the bill and I'm very appreciative that has experts--rather than sales-focused pushy people--to help you make the right decision. I've pulled my trailer with ease and the Strait-Line has lived up to every expectation. And's price was great and the shipping had it delivered sooner than expected. It's rare when you can say you are COMPLETELY SATISFIED with a product, service, quality, and price--but I can that about my purchase of the Strait-Line RP66084 from

Greattowed trailer through wind and hail on way to Floridasure glad I had this hitch setup!
Ken W - 06/01/2016


The sway control worked OK when the hitch was new but after 8000 miles and as the hitch wore in, my 32 foot trailer became harder to control as the trailer mounted sway brackets developed flat spots on the rollers - the grinding noise which got worse as the hitch heated up from the vehicles exhaust has become unbearable. I have elected to order a different hitch / sway system which unfortunately is not sold by etrailer.

I have reached out to my contacts at Reese regarding your concerns about your Straight-Line weight distribution system and get the following information that I wanted to pass along you you: It is normal for the dual cam portion of the hitch to develop wear or flat spots on the rollers. The spring bars constantly move fore and aft on the dual cam and they will wear. We maintain this metal on metal friction to minimize sway. Yes the metal on metal contact will create noise when making turns and more noticeable when making turns at slow speeds. This is all part of how the system works with all the parts and pieces.

this is exactly what we needed
for a weight distributing hitch w/sway control, shipping and service was very good. Will use this company again. Thanks

Great, used this setup quite a few times in the past year, still doing what I bought it for. Thanks Steve C
Steve C - 12/24/2019


This thing works well, as advertised. It did boost the rear end of the truck up immediately and seemed to have a positive affect on sway. I was able to back up with it as advertised.

The issue I had with it and what prevents me from scoring higher is despite the fact that I followed the instructions to the letter, the lower brackets are installed by drilling out holes and hammering in "blind" or knurled nuts. I was leery of their longevity and for good reason. After 1500 miles they wallowed out the holes and made one of the lower brackets loose.

My solution was simply to weld the lower brackets directly to the frame and its vastly superior to the install methods they advise and works great. However since not everyone is comfortable/set up to MIG welding these on and will rely on the foolish blind nuts I can only give it 3 stars.


I purchase a used trailer recently and have made several purchases from etrailer to include a Straight-Line Weight Distribution Hitch (RP 66084), 2 5/16 Ball (19286), RV Generator Plug (CAM 55333), Aqua Hose, sealing trim for roof and side seams etc...

All of the products have arrived on time and are of high quality. The trunnion bar holes on the RP 66084 were missed drilled so I called etrailer(Laser) and he shipped me out replacement bars which arrived sooner than expected along with a return label for the miss-drilled bars.

Products are quality, service is quality and inventory is exceptional.

It is a pleasure doing business with them.


etrailer did a fabulous job coordinating many products for my application. I am towing a sports car hauler/ camper combination trailer with a 2014 Jeep Grand Cherokee V8. It all works extremely well. Backing up goes very well too, even if I do have limited view, I can always see one side at a minimum. Thanks for the knowledgeable staff! I had a lot of questions and wasn't entirely sure which setup would suit my situation best, and they guided me to the setup best for me.


I bought the Strait-Line Weight Distribution System w Sway Control - Trunnion Bar - 12,000 lbs GTW, 1,200 lbs TW
for my 18 foot trailer used to haul just under 10,000lbs of Tractor and implements on winding Tennessee roads with my 2014 Double Cab 4.6 liter Full Bed Tundra.
The product works great; I almost don't realize the trailer is there. Everything is level with no drop at the front and 1/2 to1 inch drop at the back depending on what's loaded. There is normally about a 3-4 inch drop in the back.

Be aware that the box will be delivered at just over 90 pounds.

The installation is not technically difficult, but you will need more tools than the instructions indicate to get everything together. The high torque bolts and as well as the 450 ft/lbs ball torque require some specific large wrenches and sockets. If you go through the instructions and pieces for the actual size of the bolts required, it will save you some running around to find tools. Invest in a step drill bit and it will save some hunting.

With everything in place and ready to go, this was a solid 8 hour install with a lot of low to the ground squatting and bending which you will feel the next day. If I were older (46 now), I would have a professional install this. If you do, they will need a fully loaded trailer to finish which you will also need to finish the install.

There is one piece in the instructions for installing the optional 1/2" x 1.00" SELF TAPPING SCREW into the snap up braket First, this is not really optional, but the instructions indicate to drill a 9/16" hole for this 1/2" screw which is incorrect and will cause you to not be able to tighten the screw down. The whole should be 1/2". Don't be tempted to put these in before the very last step after everything is hooked up or you will be very unhappy. The snapup brakets get moved around several times between the WD and Sway Control sections.

The only negative (if it is negative) is that for my trailer height of 16", the trunnions are only 5 1/2" of the ground which can make speed bumps and the like an interesting experience as the do contact the road as the trailer wheels go over those bumps.

If you are converting from a normal ball hitch off the back of the truck to this for the first time, your break away wire and safety chains will now be too short to connect to the truck (in all likely hood). You will likely need to either add to or replace those as well.

All in all, the system works great, is technically easy to install with all the correct tools and sufficient time.


I can't vouch for the product as yet, because I haven't installed it. I can however comment on the service & etrailers excellent way of updating the progress of the transaction. It was very efficiently & fast. I ordered the hitch on Sunday night and UPS drove up in front of the house on Wednesday about 1:30 pm and delivered it. That is great service by any ones standards. I've read the instructions some & it looks like it will take some time to install this unit. There are a number of tools that are needed to accomplish the task & not all of them are in just everybody's tool box. (unless you are a heavy equipment mechanic) which my son-in-law is, so I had access to everything I needed. A friend also bought this hitch & purchased all the tools needed to do the job so I am all set to strike out and install the hitch, as soon as it takes a turn for the better weather wise. The hitch is a massive heavy duty unit that looks to be able to handle the job with ease. When I get it installed & use it awhile I will repost a review concerning it's use & installation info including the quirks & all the things needed to measure & drill, etc. to put it to use. I again want to thank etrailer for their attention to every detail of the transaction & the prompt service & almost miraculous delivery in such a short time right to my door & in a complete state. (nothing missing) it was very well packaged to stand up to the rigors of shipping.Kudos Etrailer...

-- comment by: Steve - 06/14/2014


It was OK. Put it on my trailer in place of a ProPride P3 so renters could use it. Drove less than 30 miles with the Reese, and the ProPride went back on. It's a much better hitch. Trailer can't sway with a ProPride.

Got a very lightly used Reese available, by the way.


Love this. Never feel sway and being able to back up without discontecting the bars really helps. Definitely would recommend

Still very happy with the system. My neighbor has Reese envy everytime he sees me backing up without having to disconnect like he does. Highly recommendit.
Richard R - 03/11/2020


Solid product, disappointed to see it is manufactured in China but it seems quality nonetheless. Etrailer was great, quick shipping and good prices.


Pulling a trailer from Oklahoma to Wyoming and the one thing you’re guaranteed; wind and fast moving semis.

When you see enough trailers on the side of the road flipped, knowing you have the additional help off the bat to control your own is peace of mind worth the price. Pulling through 80mph crosswinds or a blizzard, having this piece of equipment is a lifesaver.

My only gripe is the install can be challenging and ended up just watching online videos. You’ll end up buying additional trailer mounts for faster hook up if you have more than one trailer.


What a piece of engineering! I haven't towed with this yet but the design looks great. I've read other reviews about how long the installation takes, the directions seem simple so I don't anticipate any problems. My unloaded, as shipped TW is 600lbs, adding a battery and full propane tanks plus the hitch weight brings the TW up to 800lbs. I should have plenty of extra capacity with these.

I just pulled 500 miles with zero sway. When being overtaken by a semi, the whole rig wants to move instead of just the camper. I find this normal and acceptable.
Edward S - 06/30/2016


Product works great for my setup, before I had a standard weight distribution system and my 37’ camper was all over but with this trunnion setup greatly reduces my white knuckle driving I experienced before.

It does take some work to install but got it done in about 3 hrs because I checked and rechecked before drilling the necessary holes in the tongue.


This is a great product, so glad I installed on our 28' travel trailer! When hooked up to the truck, the truck and trailer feel like one unit. Plan on adding the side sway mechanism next summer.


Packedge arrived a day early which is good, heavy cardboard box, little damage from the long cross counry delivery, inside all o,k.
I installed the hitch as instructed without a problem, next week I hope to have a road test, it looks well built. Dodge Ram 2500 28' toy hauler.
Thanks guys.

Thanks for your letter.Your product is preforming very well. My trailer is very steady behind my track,

  • Dual Cam Sway Control Weight Distribution Recommendation for a 29 ft Snowmobile Trailer
    Dual-cam sway control weight distribution like the part # RP66084 that you referenced is one of the best options for reducing trailer sway because it is the only system to proactively work to prevent sway before it starts. Another advantage dual-cam systems have is that they can be used in inclement weather unlike some of the other friction-based systems.

  • Can Weight Distribution and Sway Control be Used on a Vehicle with Active Air Suspension
    The dual-cam sway control brackets on the Strait-line weight distribution system, # RP66084, do require drilling into the trailer frame but the spring bar brackets do not. They are held in place with set screws. If the active air suspension system can be easily deactivated, that would be ideal. If it cannot be easily turned off, you will first connect the trailer, then let the active air suspension system adjust. Then you will hook up the weight distribution spring bars. This may cause...

    The easiest solution for you to get home (as long as you have the capacity) would be to remove the spring bars of the system and take it easy till you get home and then have it repaired.

    Since your dry tongue weight is a bit more than 10% of total weight, we will assume the same for loaded and estimate that you have a 900 pound tongue weight loaded. I prefer the pro-active, dual cam sway control systems to the reactive friction systems when talking about a toy hauler or car trailer since the load inside can sway or move too. For your set up, I would recommend Reese Round Bar Strait-Line Weight Distribution with Dual Cam Sway Control, part # RP66084. It has a tongue weight...

  • Weight Distribution for a 2006 Dodge Durango 4WD Pulling a 2 Horse Trailer
    I believe the manual is referring to weight distribution and sway control. Even with WD and sway control added, you will not gain any extra tongue weight capacity. If you are towing more than 50 percent of your vehicles weight, sway control and weight distribution should be used. I have included an FAQ on weight distribution below. To determine tongue weight, you can follow the method in the Trailer Towing Tips FAQ linked below. Generally speaking, the tongue weight should be between 10...

  • How to Set Up a Weight Distribution System on a Ford Expedition with an Automatic Suspension System
    Yes, a weight distribution system is useful on a vehicle with automatic suspension systems such as your Ford Expedition. Automatic suspensions systems will adjust to ensure that the load is level, but they do not help distribute the weight so that the weight is distributed to all axles on the truck and trailer. I spoke with our contact at Reese and suggested that the best way to utilize the weight distribution system and an automatic suspension system simultaneously is to first, start...

  • Troubleshooting Trailer Sway that Starts at a Certain Speed with Weight Distribution
    Typically when sway like you described is encountered while towing the problem has to do with the way the cargo is loaded in the trailer. If you don't have 10-15 percent of the total weight of the trailer as tongue weight you will get sway like you described. I am glad adding a second sway control unit helped your setup, but sway control units like that are not designed to stop the kind of sway you are experiencing. Try moving the weight of your cargo forward in the trailer (if possible),...

  • Weight Distribution System Recommendation for a 2015 Chevy Silverado 1500
    For a trailer that weighs 8k I would recommend you use a WD system. Especially since your owners manual say anything over 7k requires one. The best way to pick out a weight distribution system is to base it off of the loaded tongue weight of the setup when it is loaded and ready to tow. This figure also includes the weight of any cargo behind the rear axle of the tow vehicle. I attached a help article on determining tongue weight for you to check out as well. You will want the loaded...

  • Is Strait-Line Weight Distribution System w/ Dual Cam Sway Control the Best Way to Control Sway
    The Reese Strait-Line Weight Distribution Systems with Dual Cam Sway Control, is an active system which prevents sway. The cams on this system lock into position to hold the trailer steady which means sway is stopped before it can even begin where as other systems just reduce sway. The Straight-Line systems are very popular with our customers and highly recommended by us here at etrailer. As for the cams, these will not need to be replaced unless there is damage or excessive signs of...

  • Why Aren't Some Hitches Rated for Weight Distribution Systems
    Weight distribution systems put a different kind of torque on the hitch and it's vehicle mounting points than a standard non WD system setup. The force of the spring bars puts almost like a twisting forward type of leverage on the hitch from the bars trying to put the tongue weight up on to the front axles of the vehicle. What you can do is check with the manufacturer of your motorhome to see if a weight distribution system is recommended. Since it's such a high capacity hitch most likely...

  • Can a Weight Distribution System Allow a Vehicle to Tow More than Hitch Capacities
    If there is a second tongue weight capacity listed on the hitch of your truck that shows a higher capacity when used with a weight distribution system then yes, a WD system would allow you to tow a trailer with a higher tongue weight than 600 lbs. Otherwise there is nothing I can recommend for you that will allow you to tow beyond the capacities of your vehicle.

  • Loud Noise When Turning with Strait-Line Weight Distribution System w/ Sway Control # RP66084
    It is normal to experience some noise when using the Strait-Line Weight Distribution System with Sway Control, # RP66084, since there is metal to metal contact . Since you mention that it is a loud noise, I would start by greasing your hitch ball and trunnion ends to see if this will the noise that you are experiencing. If the amount of noise is still the same, I would then check the amount of tension on the spring bars and readjust the system following the manufacturers instructions....

  • Weight Distribution System for a 2017 GMC Yukon with 27ft 5200 lb Dry
    If you are trying to decide between a dual cam or friction style weight distribution system, then I recommend the dual cam system. Using a dual cam system, like the Reese Strait-Line # RP66084, will help eliminate trailer sway before it begins while the friction system will tries to correct sway after it has already started. Friction systems begin to work only after a trailer begins to start to sway. The bars use the metal to metal friction that helps bring the trailer back in line. With...
